Random thought while looking through the image thread.
His jeans look brand new. They look very stiff and too big. I'm not convinced that these are normal clothes for him. I think it's very possible that he purchased these clothes specifically to commit a crime. And specifically bought them too big to help hide his build just in case he was seen
I don't think anyone should get too caught up in what he was wearing, he could be a guy who is normally in a suit or different clothing. I think some characteristics like loner or hunter have been cast upon him based on what he's wearing. Keep in mind that these clothes could very well be new and simply what was practical for what he planned to do that day. If you know someone who shares his facial features, report it. Even if you've known him for 10 years and never seen him in jeans before.
I also don't think he has a pouch. I think he has on a hoodie(probably zip up) layered with a blue coat over it. It is lifted up on his right side as he reaches into his hoodie pocket, likely to get his weapon as he approached the girls. He is likely right handed.
The news that the camera was front facing and shot over Libby's shoulder also makes me feel reasonably sure that he grabbed Abby first and used her to control Libby, who chose to try to save her friend over running to save herself.
I know some of this has been discussed over and over. But, as I said previously, I'm playing catch up here and information shared while I was on my break from the case has firmed a few things up for me. Plus we really don't have much else to discuss anyway
